South American mummies were victims of homicide, not natural death

by

How frequent was violence in prehistoric human societies? One way to measure this is to look for trauma in prehistoric human remains. For example, a recent review of pre-Columbian remains found evidence of trauma from violence in 21% of males. So far, most studies of this kind have focused on skulls and other parts of … Read more

How do archaeologists differentiate between different periods of human prehistory?

by

Archaeologists differentiate between different periods of human prehistory through a combination of chronological dating methods, material culture analysis, stratigraphy, and interdisciplinary research. Human prehistory encompasses vast spans of time, ranging from the emergence of our earliest ancestors millions of years ago to the advent of written records around 5,000 years ago. During this long and … Read more
